Sending html messages trough phpmail()

[PatrickRQ]

Hello,

I have a little trouble sending html message, once I will set this option to yes: http://screenshooter...5311258/hoypfhn

It tells me that message cannot be sent, I base on Linux (php5), the sendmail in PHP is set to sendmail which is reference only to exim 4. So the main SMTP server is the exim (I didn't want to use sendmail itself so just used it as connector between exim and php as it didn't work directly to attach exim to php. I do like this for years anyway).


However, I am wondering what I missed and where, as exim's logs tells me nothing special that could help me to solve the issue, any advice?


P.S. tested on local copy of same forum running on windows and sending the html messages worked perfectly.

dealt with similar last night, are some domains accepting mail while others are not?
seeing any 450 4.7.1 client host rejected cannot find your reverse hostname
you have PTR setup for the server?

I have cpanel with config server mail queue plugin so I was able to easily see the errors.

only used suhosin for a bit so I am rusty.
turning mail.protect toi 0 should allow it to send at least while you work on hardening it, having it as 1 disallows exactly what it looks like its blocking.
iirc there was a bug dealing with this issue

[Dmacleo]

not a bug, its doing exactly what its supposed to do if I am reading the errors right
http://www.hardened-...in.mail.protect

can turn it off (set to 0) globally or in htaccess (iirc its php_value suhosin.mail.protect 0 ) for the domain in question turn it to 0.

[PatrickRQ]

thanks a lot, that helped.

[Dmacleo]

glad I was able too :)
